Abstract
Background: Vascular occlusive event is one of the etiologies of sudden sensorineural hearing loss (SNHL). Stellate ganglion block (SGB) induces dramatic and intense vasodilatation in head and neck. Based on this principle, SGB has used as one of the treatment modalities in SNHL. This study was performed to evaluate immediate response of SGB on pure tone audiogram (PTA) in SNHL. Methods: Forty patients were studied. Each patient received daily ipsilateral SGB in paratracheal approach using 0.2% bupivacaine for 2 weeks. On first, third, and fifth day of treatment, we checked their PTA twice 1 hour before (Pre-PTA) and after (Post-PTA) SGB. Pre- and Post-PTA were compared. Several factors were analyzed as a prognostic factor of therapeutic results. Results: Eleven of 40 patients revealed decreased PTA after SGB. Degree of decreased PTA were insignificant (
